Dual monitor setup just cuts off randomly.

[Jyeu]

Pc Specs:

Gigabyte x570i aorus pro wifi

Ryzen 7 5800x3d

msi rtx4090 gaming x trio

32GB ram

1000w PSU

 

not sure what happened but my monitors both randomly cut off when playing a game. Cyberpunk 2077 just running benchmarks. Not sure what would cause that. Any ideas? Computer is a custom loop and idk if heat would cause that but the PC is still on and running.

 

I did run another benchmark and the sound did cut off too. I’m lost.

I wasn’t able to catch the readings. I’m going to assume it’s a full PC crash because I lose sound from the PC as well as the dual monitors going black as well. 
 

Currently can’t get the PC to crash or whatever was crashing before. What I did differently was update the bios to the latest version available on gigabyte x570 series and then changed bios settings to what I had previously which was XMP for ram, curve optimizations to negative 30 (pre bios update) then upped it to negative 20 instead (post update). After that I just tried to run a benchmark of my system with maxed out 4K settings and all the new graphical settings for cyberpunk and I think it’s fixed?

Nvm. It happened again. Temps are extremely low. 40’s cpu and 50’s gpu. Whole PC crashes but the computer still runs.

Figured it out. Custom cablemod PCIe cables wasn’t delivering enough power.
